CARVINGI-MACHINE.

SPECIFICATION forming part of Letters Patent No. 470,450, dated March 8, 1892.

Application filed August 27, 1888.

To 00% whom it may concern:

Be it known that I, lVILLIAM S. SEAMAN, of Milwaukee, in the county of Milwaukee, and in the State of WVisconsin, have invented certain new and useful Improvements in Carving-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

Y. My invention relates to wood-carving machines, and will be fully described hereinafter.

In the drawings, Figure 1 is a perspective view of my invention. Fig; 2 is an end View. Fig. 3 is a front elevation of one front corner Fig. 4 is a plan View of this corner with the table removed. Fig. 5 is a broken plan of the tool-frame. Fig. 6 is a front sectional elevation of the tool-frame and the connections by which it is suspended from abalanced supporting-frame. Figs. '7, 8, and 9 are details.

A is the stand of myflmacliine, and B are arms that extend outand up from it to support a balanced frame 0, from which the toolframe is suspended. The arms 13 are solidly connected by a bar B, and a knife-edged plate a is set firmly in a lug a',that is bolted to the upper end of each arm B, on each of which knife-edges rests one end of the central shaft or bar 0 of the frame (Leach of which ends is formed with a wide V-shaped groove to receive the knife-edge. The arms of frame 0, of which there are three, I) b b, are preferably connected at their rear ends by a cross-bar c, and the front ends of arms I) b are formed or provided each with a spanner cl, and in each of these spanners is swiveled a gimbalring 6, to which in turn is swiveled the arms of a spanner f, from which an arm D is hung. The arm I) is also formed or provided with a spanner b and in this spanner the studs 9 of a hanger h are trunnioned, and lugs h of spanner h are swiveled to the arms '5 of a spanner E, from the base a" of which the central supporting-arm E of the tool-frame is suspended. The hub j of spanner E forms the upper bearing of a shaft F, and the lower bearing of this shaft is formed by a hub Gin an arch G, which arch is suspended from the arm E, in which latter the shaft F is housed. On its upper end shaft F carries a single sheave K, which is connected by belt K with anysuitable driving-power. On its lower end Serial No. 283,858. (No model.)

the shaft F carries a double sheave L, which double sheave is connected by belts M with the shafts M of the tool-holders m. a The lower ends of the arch G have swiveled to them an arched gimbal-ring p by means of pointed bolts 19, and to arms qof this gimbal ring 19 are swiveled the arms N N of a guiding-tool holder N in the lower end of which is fixed the guiding or tracing tool a. The arm N of the guiding-tool holder N projects up higher than arm N and is pivoted to a bar R, which in turn is pivoted at each end to an arm R of a sleeve M which sleeves M form the bearings that the shafts M" of the tool-holders m revolve in. The arms R and blanks are secured in any suitable manner.

T-ribs S are bolted to the under side of the table, and the lower ends of these ribs, which arebeveled, fit in grooved cleatsT, that rest onandare secured to other grooved cleats T, [whichare bolted to a frame U and slide on the beveled upper edges of girders V, that are bolted to the frame A. By my construction the tracer and the tools are so connected that any movement of the former is positively communicated to the carving-tools.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a carving-machine, of a suitable stand, arms extending up from the stand, a bar connecting the arms, a lug secured to the upper end of each of said arms, a plate projecting from each lug, a shaft having both of its ends formed with a groove for engagement with the plates, a balanced supporting-frame carried by the shaft, arms suspended from the frame, a tool-frame suspended from the arms, swiveled connections between said arms and supporting-frame and the tool-frame, a guiding-tool and its holder,

of a balanced supporting-frame comprising three arms, a cross-bar connecting the rear ends of the arms and spanners extending from thefront endsof said arms,-a gimbalring h'avi ngit's bearings in each of the two outsidespa-nners of the'frame-arms,two depending arms having spanners at their upper ends swiveled to the gimbal-rings, similar spanners projecting from the lower ends of said arms, a tool-frame, gimbal-rings connecting. the latter spannerswith the outer-ends of the t0 0lframe, a centrally-depending hollow arm havinga spanner at its upper and lower end, a hanger swiveling the upper spanner of the hollow arm to the spanner of the inner arm of the supporting-frame, aguiding-tool-and its holder, the latter being swiveled tosaid tool frame and the spanner at the lower end of said hollow arm, carving-tool holders and their bearing-sleeves, the latter pivoted to said tool-- frame, a bar pivoted to arms of the bearingsleeves and to an arm of the guiding-tool holder, a shaft suitably arranged in the central depending hollow arm,pul'leys carried by the shaft, pulleys alsocarried by the shafts of the tool-holders,andbelting connecting'thedriving-shaft with a suitable driving-power and with the pulleysof thetool-holder shafts, substantially as set forth.

3. The combination, in a carving-machine,-

of a suitable stand, girders secured to the stand, cleats having grooves for engagement with the upper-edges of the girders, a frame fastened to'the cleats, other grooved cleats secured to the first-namedcleats, and a table ing both of its ends formed with a groove for engagement with the plates, a balanced supporting-frame carried by the shaft and comprising three arms,a cross-bar connecting the rear ends of the arms and spanners extendin g from the front ends of said arms, a gimbalring having its bearings in each of the two outside spanners" of the frame-arms, twodepending arms having spanners at their upper ends swiveled to thegimbal-rings,-similar spanners projecting from the lower ends of said arms, a tool-frame,gimbal-rin gs swivel-ing the latter spann'ers' of thearms to the outer ends of the tool-frame, a centrally-depending hollow arm 1 having a spanner or arch at its upper and lower end, a hanger swiveling the upper span- ,ner of the hollow arm to the spanner of the inner arm of the supporting-frame, a guidingitool and its holder, the latter being swiveled' @to said tool-frame and the spanner at the ilower end of said hollow arm, carving-tool- ?holders and their bearing-sleeves, the latter pivotedto said tool'-frame, an arm project-ing gfrom' each of thebea-rin'g-sleeves and fromthe guiding-tool holder, a-barpivotedtothe arms,

a shaft suitably arranged in the central depending hollow arm, pulleys carried by the 5 shaft, pulleysalso carried by the shafts of the 5tool-ho1d-ers, and belting connecti-ngthe drivfing-shafts with a suitable driving-power and with thepulleys of the tool-holder shafts, substantially asset forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee. in the county of Milwaukee and State of- Us cousin, in the presence of twowitnesses.
